| Abstract: |
| Three kinds of antioxidant were added in each nylon heat insulation strip materials (PA66-GF25) individually; the effect of antioxidant was characterized by change of tensile strength of nylon heat insulation strips after aging. The results indicated that all of the antioxidant prolongs the aging time of the materials; the best is ternary compound which contains C-centered radical scavengers. Besides this, the static service life of nylon heat-insulation strip material is also predicted through theory of computation; the materials without antioxidant can be used only about 4.34 years, while the materials with ternary compound have service life of 57.05 years. |
